Embodiment 1

[0028] Such as figure 1 As shown, a kind of quick-frozen soft-shelled turtle processing technology of the present embodiment comprises the following steps: 1) Use soft-shelled soft-shelled turtles as raw materials: live soft-shelled turtles bred in ponds for 3-5 years must be disease-free and pollution-free, each weighing 500g -700g. 2) Neck-cutting and bloodletting: When using neck-cutting, attention should be paid to the depth of the knife edge. The neck of the soft-shelled turtle should not be cut off or too deep, which will affect the appearance of the product and cause difficulties in sales. 3) Soak the soft-shelled turtle treated in step 2) in hot water at 90°C-95°C for a few seconds, then manually remove a layer of outer membrane in warm water at 30°C-40°C. 4) The soft-shelled turtles that have been removed from the film should be cut open on the abdomen or rounded on the back. It is required to have a small part of the back attached to avoid complete separation; the ...

Abstract

The invention discloses a processing technology for a quick-frozen soft-shelled turtle, which comprises the following steps of: 1) using living soft-shelled turtles as raw materials; 2) cutting the necks of the soft-shelled turtles to slaughter the soft-shelled turtles to drain blood; 3) manually removing outer surface membranes; 4) crossly opening the bellies of the soft-shelled turtles or circularly opening the backs of the soft-shelled turtles; 5) clearing all internal organs and grease; 6) shearing off all nails of the soft-shelled turtles; 7) washing the soft-shelled turtles with tap water; 8) checking one by one; 9) degreasing and removing smell by using composite salt solution; 10) draining water and rinsing for 30min, 11) draining water after rinsing, and treating the meat of the soft-shelled turtles by using food antifreeze agent, water-retaining agent and antioxidant; 12) vacuum packaging; 13) enabling central temperature to rapidly reach a value below 18 DEG C below zero for quick freezing; and 14) conducting freezing storage under an environment below 18 DEG C below zero to obtain finished products. The processing technology for the quick-frozen soft-shelled turtle has the advantages that not only can the problem that the brought soft-shelled turtles are difficult to slaughter be solved, but also the soft-shelled turtles can be sold in the market all year round and the soft-shelled turtles are convenient to preserve.

Description

technical field [0001] The invention relates to a quick-frozen soft-shelled turtle processing technology. Background technique [0002] Chinese soft-shelled turtle ( Trionyx sinensis ), commonly known as soft-shelled turtle, belongs to the order Testudinata, the family Trionchidae, and the genus Turtle ( Trionyx ). At present, there are hundreds of species of turtles and turtles in the world, but there are only 2 genera and 3 species in my country. The Chinese soft-shelled turtle is mainly bred in China. It is a precious economic animal. It not only has delicious meat, rich nutrition and high protein content, but also all parts of the body can be used as medicine, which has the effects of nourishing and strengthening the body, anti-cancer and anti-aging. In recent years, under the guidance of relevant national macro policies and the support of local governments at all levels, soft-shelled turtle farming has developed rapidly. The breeding of soft-shelled turtles was onc...
